...first i was on low BB,than i figure it out that i need longer bike.Last year in June i bought GU Typhon.Now i'm back on low BB,me and my mate swap frames, i have his ZOO! PItbull 04 1075mm WB and he has my Gu typhon 1095WB. ...what i found is that i can't gap on high BB,i have 20cm longer gaps with ZOO!.I can tap with GU,but with 100% concentration,bunnyhops,hoo hoas,gaps to front are easier with high bb(at least to me).Sidehops to me are pretty much the same on both bikes,but i've learned to do decent sidehop on high bb .Balance on the rear is easier with high BB,but now i don't have problems to stand still even on low bb,i think that high bb has helped me to learn this faster. ...i couldn't test differences like i would want to. We have to much of snow.If you have chance try different frame geometries to find what suits you. ...also found that newbies learns faster on high bb than on low bb-easier to balance.
